CHURN=MOTOR.

SPECIFICATION forming part of Letters Patent No. 246,466, dated August 30, 1881.

Application filed March 12, 1881.

To all whom tt may concern:

Be it known that I, JOHN N. (JRETOHER, a citizen of the United States, residing at Pierceton,in the county of Kosciusko and State of Indiana, have invented certain new and useful Improvements in Churn-Motors; and I do hereby declare the following to he afull, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to letters or figures of reference marked thereon,which form a part of this specification.

This invention relates to certain improvements in churn-motors, especially of that class operated by clock mechanism.

My invention consists in the novel construction and combination of parts, as will be hereinafter more fully set forth and specifically claimed.

Figure 1 of the drawings is a side view of the churn with the rear part partly in sect-ion to show the brake and stop device. Fig. 2 is a plan view of the clamping-ring embracing the dasher-rod. Fig. 3 is a plan view of the dasher.

In the annexed drawings, forming a part of this specification, the letter A represents a frame constructed with a platform for a churnboX, B, and a rectangular box, C, at the top for the clock mechanism. The rear wall or post ot'the frame is formed with two openingsone for the passage of the winding-up shaft and the other for the brake and stop-screw b, with the milled or burred head, as shown in Fig. l of the drawings. This brake and stopscrew I), formed with screw-threads, engages with a nut arranged in the passage (1, and the face-plate supporting one end of the clock mechanism, so as to secure an adjusting property. The inner end of this adjusting-brake and stop device engages with the flat surface of the master-wheel c, as seen in Fig. 1 of the (No model.)

drawings. The master-wheel c engages with a pinion, (I, mounted on the transverse shaft 5 e, carrying on its outer end a crank,f, to which is connected by suitable means the pitman h, as seen in Fig. 1 of the drawings.

The letter D (see Fig. 2) represents the ring for securing the dasher-rod to the pitman. This ring is composed of two semicircular sections, k 70, hinged at l, and provided with an automatic locking device. The section It is formed with a stem or shank, m, for the at tachment to the pitman, and anose or beveled projection, n, and the other section, k, is provided at its outer end with the spring-catch s, to engage with the nose n, and with a clamping-screw, t, to connect the rod carrying the dasher to the ring and pitman, whereby the desired reciprocating or vertical motion is given to the dasher.

The upper ring, E, which merely serves the purpose ofa stationary guide-ring, is constructed in two sections and provided with the spring locking device similar to that shown in Fig. 2.

The letter F (see Fig. 3) represents the'opeuwork dasher. This dasher may be cast in a single piece and afterward galvanized, so as not to affect the cream or take rust; or the presence of two witnesses.
